CATDOLL : CATDOLL: When raising crayfish, I put some loaches into the mix, but why were there no loaches left later?

1. I raised some loaches with crayfish, but why were there no loaches left later?

There are fewer and fewer wild loaches in rural areas now, and they have even become extinct in many places. Many uncles who farm in rural areas said that they used to step on loaches in the fields, but now they can't catch a loach even if they turn the whole field upside down. I believe this situation is the same in many places now. We can't blame others for this. We can only blame ourselves for overusing herbicides when farming to save trouble. Herbicides are very toxic. Not only can they kill loaches directly, but they can also poison loach eggs. So now there are no eels and loaches, and the ultimate culprit is the excessive use of herbicides.

In recent years, more and more people are raising loaches and crayfish. In order to improve the breeding efficiency, some farmers will mix loaches and crayfish. If you are inexperienced, you may think that there should be no problem with the mixed breeding of the two, and they can live in peace and grow together. But the truth is far from as simple as imagined.

Just like what the questioner said, when raising crayfish, a lot of loaches were put into the shrimp pond, but in the end, when the pond was dry and messy, there was no loach. I think this situation should have been expected from the beginning. Crayfish is a creature with extremely strong vitality and is also an omnivorous animal with a very fast reproduction capacity. If crayfish and loaches are raised together, the number of crayfish will definitely exceed that of loaches. The two will inevitably compete for living space, and crayfish are ferocious in nature. If food is not delivered in time, they are likely to catch loaches for food.

Although loaches are also good at digging holes, they are nothing compared to crayfish. Even if loaches hide deep, as long as the density of crayfish reaches a certain level, there will be no room for loaches to survive. Generally, when the two are mixed, loaches will become food for crayfish, and half of loaches live on the soil, which makes them easy to be preyed upon by crayfish.

Therefore, the phenomenon that the questioner encountered is undoubtedly that the loach was eaten by the farmed crayfish. Therefore, when breeding crayfish, it is best not to breed loach together, as it is difficult for the two to coexist peacefully. Moreover, crayfish grow too fast. Even if you raise the loach and then put in the crayfish seedlings, the growth rate of your crayfish will be much faster than that of the loach, and eventually the loach will become food for the crayfish. Therefore, it is recommended not to breed the two together. What do you think?

Because they were all eaten by crayfish. Although crayfish eat grass, they still like to eat meat. They like loaches even more, so they should not be raised together.

2. How to check whether there are loaches and crayfish in the fields? Thank you everyone!

1. Mainly look at the holes, see if there are small holes on the edge of the field.

2. The size of the hole. Loach holes are relatively small, and the walls of the holes are very smooth. This is because loach bodies are smooth and they often go in and out. Lobster holes are slightly larger and rougher.

3. How to distinguish whether there are lobsters or loaches in the hole. The water in the hole with loaches is relatively turbid because loaches will move in the hole and make the water turbid. If the water is clear, it means there is nothing in it.

4. Look at the traces at the hole. If there is a loach hole and the soil is relatively thin, the loaches will leave traces of their swimming at the hole when they go in and out.

3. Can loaches and shrimps be farmed together?

Can.

Breeding precautions

1. Pond environment

The pond should be close to a water source to facilitate regular adding of water to the pond. Generally, the area of ​​the pond can be 1-3 mu. The water depth of the pond should be 50-60 cm. The bottom of the pond should be flat and free of silt. Anti-escape measures should be taken. Use 50 kg of quicklime mixed with 15 kg of bleaching powder per mu to disinfect the pond.

2. Provide enough basal fertilizer

Before stocking loach seedlings in the pond, it is necessary to apply sufficient base fertilizer and cultivate biological bait. Poultry and livestock manure can be chosen. Normally, 10-15 kilograms of fertilizer is applied per square meter.

3. Stocking of seedlings

40-50 3-4 cm loach seedlings are placed per square meter of water surface. When the loach seedlings are placed in the pond, they need to be soaked in 3-5% salt water for 5-10 minutes to avoid diseases such as saprolegniasis.

4. Feeding

Generally, the compound feed with 30% protein content is fed, and the feed is about 4%-5% of the body weight of the adult loach. When the temperature reaches 25℃-28℃, the loach eats a lot, so more feed should be fed appropriately to help the loach grow better and faster. When the water temperature is higher than 30℃ or lower than 10℃, the amount of feed should be reduced accordingly. Adhere to the "four fixed" feeding, and it is generally best to feed in the evening.

5. Water quality management

The pond water should be yellow-green in color, with a transparency of 20-25 cm. When the water color turns into tea brown, dark brown, or the dissolved oxygen content in the water is below 2 mg/L, the water should be changed in time. Residents should regularly use beneficial microbial preparations to keep the water rich, active, tender and refreshing.

6. Daily management

Monitor the water temperature of the pond in real time. When the water temperature is above 30℃, inject new water to lower the water temperature and increase the dissolved oxygen in the water. In addition, patrol the pond and solve any problems immediately.

7. Technical points and precautions

Anti-escape facilities must be complete, the quality of loach species must be strictly controlled, feed must be carefully inspected, waste is strictly prohibited, and water quality and diseases must be well controlled.
